FRANK WILSON, s3; OF'LOS ANGELES, oALIFoImrA,--AssIeNoR T0. ANNIE WILSON RAIL AND TIE CLAMP.

Application filed May 3, 1927. Serial No. 188,580.

My invention relates to devices used in railway construction and more particularly to a clamp for fastening rails on ties, this clamp being an improvement on my rail and tie clamp patented December 28, 1926, under Patent N 0. 1,611,977.

The object of my present invention is to provide a simplified and improved rail and tie clamp for rigidly binding the rails to the ties so that there can be no spreading or tipping of the rails, whereby accidents may be caused, nor any cutting of the rails into the ties so as to induce premature decay therein.

Other objects and advantages will appear hereinafter and while I show herewith and will describe a preferred form of construction, I desire it to be understood that I do not limit my invention. to such preferred form but that various changes and adaptations may be made therein without departing from the spirit of my invention as hereinafter claimed.

Referring to the drawings which accompany this specification and form a part thereof,

Fig. 1, is a plan View of a small section of a railway, in the construction of which my improved rail and tie clamp is used;

Fig. 2, is an enlarged end view, in elevation, of a tie, and a fragment of a rail clamped thereto, by means of my improved rail and tie clamp.

U-bolt 11. The plate ismade of a rectangu lar piece of rather heavy plate metal, somewhat wider than the bottom of a rail and somewhat longer than the width of a tie, so that when it is placed between the rail and the tie, longitudinally of the former and transversely of the latter, its edges project beyond the flanges of the rail and its ends project beyond the sides of the tie.

agonally opposite corners thereof, and end lugs 13 are left on diagonally opposite corners thereof, which project beyond the vertical lugs. The outer corners of vertical lugs 12 are cut off as at 1 1 and slots 15, shaped to receive the flanges of a rail are cut therein, just above the surface of the plate, from the center toward the sides thereof. Holes 16, adapted to receive the ends of a yoke or large U-bolt, are made in end lugs 13.

The U-bolt 11 is made so large that the space between the branches 17 thereof is somewhat greater than the width of one of the ties employed in the railway construction, said space corresponding to the space between holes 16 in plate 10.

The use of the two parts to form a clamp is illustrated in Figs. 1 to 3 inclusive. The plate part'of the clamp is slipped onto the end of a rail 18 with itsfianges 19 in slots 15 and its web 20 between vertical lugs 12. v

U-bolts 11 are placed in a slightly diagonal position under the ties 21 with branches 17 extending upwardly through holes made in the rail flanges and through holes 16 in the plate. Washers 22 having a thicker and a thinner side to compensate for the increasing thickness of the rail flanges 19, from the sides toward the center thereof, are placed under the nuts 23 which are screwed onto the projecting threaded ends of the U-bolts. Said projecting ends are finally battered down so that nuts 23' are securely riveted thereon. The top of each of the vertical lugs 12 abuts against the under surface of the head of the rail thus more effectively bracing the rail from each side thereof.

It will be seen that this form of clamp securely and rigidly binds the rail to the end of each tie so that there is no danger, of any loosening or spreading of the rails. Furthermore, lugs 12 being in contact with the web of the rail on both sides thereof, at regularly spaced intervals, and terminating under the head of the rail, as shown in Fig. 3, serve as braces which prevent any possible tipping of the rail.

Having thus illustrated and described my invention, I claim: 7

In combination with rails and ties, a clamp comprising a plate placed between the rail andtie, bracing flanges struck up vertically andin spaced relations to theside edges of said plate and engaging in an edgewise man- 1 upstanding flanges, and fastening bolts ex- 15 tending through said alignedvholes.
